 ### Conditional statements with 'cond'
-```(doc cond "this is the documentation for cond")```
 The ```cond``` statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed. 
 
 ```(doc cond "this is the documentation for cond")```
 
-Examples are given below:
-
-```clojure
-(defndynamic cond-internal [xs]
-  (if (= (length xs) 0)
-    (list)
-    (if (= (length xs) 2)
-      (macro-error "cond has even number of branches; add an else branch")
-      (if (= (length xs) 1)
-        (car xs)
-        (list
-         'if
